I don't know what to say about that. It certainly seems odd, but I have no
idea how github decides such things. On bitbucket, you tell it the language
explicitly, which sidesteps the whole problem.

You might try what Walter likes to suggest and put

// Written in the D programming language

at the top of your D source files and see if that helps.
